SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 368,960, dated August 30, 18.87.

. Application filedAMay 25, 1887. Serial No. 239,286. (No model.)

To @ZZ whom. it may concern:

Be it known that I, WALTER F. MoRsE, of Norwood, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Sash-Fasteners, of which the following is a description suiiiciently full, clear, and exact to enable any person off; Fig. 2, a vertical transverse section of the same, taken online a: .r in Fig. l; Fig. 3, a like view taken on lineg/ yin Fig. l; Fig. 4, a horizon-tal section taken on line z z in Fig. 2, and Fig. 5 a like view taken on linem m in Fig. 2.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

Myinvention relates' more especially to that class of sash-fasteners which are inserted in the casing of the Window and are adapted to engage the stile of the sash; and it consists in a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, the object being to produce asimpler and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation:

I n the drawings, A represents the windowcasmg, B the stile of theupper sash, C the stile of the lower sash, and H the framework of the window.

rIhe outer edge of each of the stiles B C is provided with a Vertical centrally-disposed groove, in which is secured a toothed or serrated rack, b, (see Figs. 3 and 4,) said racks being so arranged that the ends of the teeth are flush with the edges of the stiles. Mortises G are cut in the frame-work H slightly above and below the meeting-rails of the sashes, and the casing A is provided with openings i, corresponding with said mortises. Metallic plates K are disposed in the mortises G, said plates being adapted to Work laterally therein, and provided at their outer ends with inwardly-projecting iianges Z, having teeth p adapted to engage the serrations in the racks b. Plates J are respectively secured to the casing A over the openings ,said plates being provided with a horizontally-arranged stud or nipple, d. A push-rod, g, is fitted to work horizontally in a hole in' said stud, and provided at its outerend with a knob or handle, h, the inner end of said rod being centrally and rigidly secured to the Iinner end of the plate K. Acoiled spring, k, is disposed around the rod g within the hole s in the stud d, said stud being counterbored to receive the spring, which acts eXpansively to force said rod outward. A plate, r, provided with a vertical slot, to, is disposed on the stud d in such amanner that it can be moved vertically thereon. The upper end of said plate is provided with an outwardly-projecting flange, t, and downwardly-projecting flange o, having a Vertical slot, 14, and when the plate r is forced downward on the stud d the neck of said knob enters the slot 14, and thereby prevents the rod g from being forced inward or outward, as the case may be.

It will be understood that the fastening for the stile B is provided with a longer plate K than the fastening for the stile C, as it is required to reach to the center of the stile B, so that its toothed iiange Z will engage the serrated bar b in said sash.

In the use of my improvement, when the sashes are closed and locked, as shown in Fig. l, if it is desired to open the window, theknob h is pressed inward, thereby disconnecting the teeth p from the serrations of the bar b and permitting the sash to be moved in a manner which will be readily obvious without a more explicit description. By moving the plate r downward on the stud d until the neck of the knob 7L enters the slot 14, (see Fig. 2,) the spring 7c may be kept depressed and the teeth p of the plateK disengaged from the serrations knob h and spring k, the plate K, having the 1o of the rack b, as described, until it is desired to flange Z, provided with teeth p and the serloek the Window again. rated rack b, said plate 1 being mounted 0n the Having thus explained my invention, what stud d and adapted to engage the knobh, sub- 5 I claim isstantially as described.
